Hi Marladene,

You will need to access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is ***** 6000, enter 2 7 8 3.
